Genealogical information. From back end of notebook CSP wrote twentyeight numbered pages beginning with an attempt to define "real." The page numbered 28 is dated November 5, 1909. In addition there is material on topology, theory of multitudes, secundals, existential graphs, and calculations, much of which are evidently concerned with the old map-coloring problem.
